The fetus is relatively stable above the 10th week of pregnancy, and the placenta gradually forms after the 10th week of pregnancy, a time when hormones can be secreted by the placenta to maintain a stable pregnancy. After 10 weeks of pregnancy, as the placenta forms and establishes its function, it can start to secrete the corresponding hormones, and it is relatively stable, therefore, the chances of miscarriage, preterm labor and other symptoms after 10 weeks of pregnancy are lower than those of early pregnancy. However, there is still a possibility of miscarriage, fetal arrest and preterm labor after 10 weeks of pregnancy. Although the fetus is relatively stable after 10 weeks of pregnancy, it is still important to take rest, avoid overwork, and do all the checkups during pregnancy. If there is any abnormality, you need to go to the hospital in time, and the doctor will formulate an individualized diagnosis and treatment plan according to the specific condition, so as to avoid delaying the condition.
